## Homework
* Download Bitcoin/OurChain source code, compile it, and run it.
* Suppose many people throw many-face dices in many rooms. The one with the hash value of the number thrown and room ID less than or equal to some number target wins, i.e. SHA256(number thrown, room ID) ≤ target. How do we estimate how many times the winner threw?
* Each team discusses how to build a paper tower with 10 A4 used paper in 10 minutes using only hands, with no tape, glue, knife … The higher, the better. Send a photo < 3MB and a text file, the smaller, the better, (to a blockchain) to prove your work.
